ROOFING.

SPECIFICATION forming part of Letters Patent No. 391,237, dated October 16, 1888 Application filed January 25, 1888.

To all whom it may concern:

Be it known that I, CHARLES M. GARRISON, a citizen of the United States, residing at \Vichita, in the county of Sedgwick and State of Kansas, have invented certain new and use ful Improvements in Roofing, of which the following is a specification.

My invention relates to a method for making a covering for roofing and other purposes.

The object of my invention is to provide a flexible water-Maud fire-proof fabric; and LOHIIS'GIKFIE consists of a sheet of woven metalli c gi e i n combination with a water 'and fire proof materiahwhich is filled in the meshes or interstices of the sheet, so as to cover and inclose the same, as more fully hereinafter specified. I

In practicing my invention I take a sheet of woven metallic wire of anysuitable length and width,and coat or incorporate with it a cement composed of aspl alt uni, coal-tar, animal-hair, and sand. This may be applied in any convenient manner, but preferably by drawing the sheet of woven wire through a suitable tank or vessel Containing the melted cement-,which is kept in aliqnid condition during the operation by meansof heat. The proportions of the ingredients may vary within certain limits Without changing the nature of my invention; but for general purposes the following proportions answer well-viz., asphaltum, ten parts;

Serial No. 261,910. (No specimens.)

coal-tar, seventeen parts; sand, seven parts; animal-hair, one part.

The asphaltum and coal-tar are melted in a suit-able vessel by the aid of heat, and the other ingredients are thoroughlyincorporated therewith. When in proper condition, and while still heated, the woven-wire fabric is drawn through the compound, by means of which the meshes become filled,the ceinent snbsequently a fiexible wgter and fire proof material.

Tdprevent' stickiness or theadhesion of the material when rolled as it leaves the cement and before cooling, it may be dashed with fine sand or equivalent material, and to solidify the whole the fabric is passed between heavy pressingrollers.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

A flexible water and fire proof fabric composed of a sheet of woven metallic wire having incorporated with it a flexible cement composed ofasphaltum, coal-tar, sand,and animalhair, in about the proportions named.

In testimony whereof I affix my signature in the presence of two witnesses.
